Product Overview
The SmartClass OLA-54/-55/-55M Optical Level Attenuators are future-proof, improved variable attenuators for fiber system testing as well as installation, maintenance, and production of multimode fibers (OLA-54) and singlemode fibers(OLA-55/-55M). The OLA-55M Motorized Optical Level Attenuator provides in addition an implemented power meter for stabilized level controller applications.
The SmartClass OLA-54 and OLA-55 Optical Level Attenuators can be part of a SmartClass Optical Test Kits that contain all of the tools, including instruments and accessories, necessary to perform professional-grade power or loss tests in the field.
| Key Features |
| Robust, shock-proof, and splash-proof design for field operation |
| USB port for remote operation |
| Absolute and relative attenuation setting |
| Level controller function for direct setting of attenuator output level (OLA-55M) |
| 40 Gbps ready due to low Differential Group Delay |
| Traceable measurements to NIST/PTB standards for confidence in accuracy |
| 600 adjustable wavelengths for the OLA-54 and 400 adjustable wavelengths for the OLA-55/55M |
| Long battery operation time of >1000 h (OLA-54/-55) |
| Benefits |
| Reduce testing time with a quick start operation, requiring no warm-up time |
| Provide excellent overall accuracy in use with hundreds of calibrated wavelength |
| Reduce the need for couplers and additional instruments in test setups. |
| Minimize insertion loss due to a special optical design |
